lodion or Canadian balsam; the outer surfaces of the assembly arecovered with thin plastic sheets 34. The nature of the plastic may varydepending on the particular function to be performed by it.

Where the wearer requires protection from strong sunlight or otherobjectionable radiation from an elevated source, shield 21 may bepartially covered with an opaque member 35 shown in Figures 7 and 8,which has slots 28 through which bolts 26 extend. By means of slots 28member 35 may be adjusted to cover more or less of the upper surface ofshield 21. Bail 22 is pivoted on bolts 20 as above explained, and cantherefore be adjusted angular-ly and clamped in adjusted position bynuts 2|. When the shield is not needed, it can be moved upwardly to anyangular extent and may be adjusted so as to obtain the positionthatgives the greatest comfort to the wearer and the best results.

Visor 21 has no prism and protects vision by virtue of its thickness. Itreects light from its plane upper surface and deiiects the light andprevents harmful rays from reaching the pupils and, at the same time,does not rob the eyes of the light necessary for proper vision.

The invention, as above pointed out, is of general utility and thematerial employed'in the glare shield is selected from those whosephysical characteristics adapt them for performing the desiredfunctions. Certain kinds of colored glass and plastics give protectionfrom violetV rays, others fromVX-rays, and other more particularly fromthe suns rays, etc.

Having described the invention, what is claimed as new is: Y

1. An eye protector and glare shield, comprising in combination, anendless head band, means engaging the top of the head for limiting thedownward movement of the band, comprising at least one strap attached atits ends to opposite parts of the band, a substantially U-shaped bailpositioned with the rear surface of the base closely adjacent the frontouter surface of the band, the two legs extending rearwardly along thesides of the band, means effect,- ing a pivotal connection between therear ends of the legs and the band whereby thebail may be tiltedrelative to the plane of the band, means latching the bail relative tothe band in several positions, two spacer blocks attached to the frontsurface of the base of the bail in positions equally spaced from thecenter of the base, the front surfaces of the blocks being downwardlyand forwardly inclined, a glare shield attached to the inclinedsurfaces, and an optical lens carrying frame attached to the base,between the spacer blocks, said frame having lenses positioned in theline of vision of the wearer.

2. A device in accordance with claim 1 in which the head band andsupport strap are coveredwith cloth, shaped to conform to the shape ofthe wearers head.

3. An eye protector and glare shield having a head band, a bail ofsubstantially U-shape positioned with the legs of the U embracing thefront of the band, the ends of they legs being pivotally connected withthe head band'to permit adjustment relative -to the plane thereof, meansfor clamping the bail in adjusted position relative to the head band; aglare shield attached to the front side of the base of the bail, saidattaching means comprising two boltsv attached to the base of the bail,projecting forwardly therefrom, the glare shield having'two openingsspaced -4` to receive the bolts, whereby it may be clamped in positionby means of nuts applied to the bolts, and a spectacle frame attached tothe bail beg tween the bolts.

4. A device in accordance with claim 3 in which an opaque planar memberis positioned on the outside of the glare shield, said planar memberhaving transverse slots for reception of the shield attaching bolts,whereby the opaque member may be adjusted relative to the glare shield.

5. An eye protector and glare shield, comprising a bail having a pair ofleg portions and a bight portion therebetween, means comprising anendless band for securing the bail to the head of a user in a positionsuch that it extends around the users forehead, and an elongated flatglare shield of relatively thin transparent material disposed in frontof the bight portion, means se-'A curing the glare shield to the bightportion in an inclined plane extending forwardly and downwardly from theusers normal horizontal line of vision, the lower edge of the glareshield being normally disposed above said horizontal line vof visionwhereby the latter is unobstructed, and an opaque sheet Vof materialoverlying at least a portion of the transparent sheet on one face of thelatter.

6. An eye protector and glare shield, compris-v ing a bail having a pairof leg portions and a bight portion therebetween, means comprising anend-A less band for securing the bail to the head of aV user in aposition such that it extends around the users forehead, and anelongated flat glare shield of relatively thin transparent materialdisposed in front of the bight portion, means securing the glare shieldto the bight portion in an Y inclined plane extending forwardly anddown. wardly from the users normal horizontal line of vision, the loweredge of the glare shield being normally disposed above said horizontalline of vision whereby the latter is unobstructed, a spectacle frame,and means for securing it to thebail in a position depending from thelatter.

7. An eye protector and glare shield, comprising a bail having a pair ofleg portions and a bight Vportion therebetween, means comprising,"

an endless band for securing the bail to thehead of a user in a positionsuch that it extends around the users forehead and an elongated natglareshield of relatively thin transparent material 'dis' posed in frontof the bight portion, means secuning the glare shield to the bightportion in an in-AVV clined plane extending forwardly and downwardlyfrom the users normal horizontal line of vision,`

the lower edge of the glare shield being normally disposed above saidhorizontal line of .vision whereby the latter is unobstructed, saidglareshield comprising a sheet of transparent glass having a transparentplastic sheet of material attached to one face thereof.
